Detailed Description

Parent class for all cameras with control over the lens system, including zooming.

Cameras without zoom shall set the maxZoom parameter to 0. When deriving a camera, please add all values (which can be set) as parameters to allow construction with application specific settings. During operation value setting by a specific method is more efficient as by setParameters. Camera constants, e.g. the max. and min. focus, should be defined as constant parameters.

Please note that the camera may take a little while until a focus, zoom, etc. position is reached. Thus the values in the parameters and those returned by the get-methods may differ.

The parameter functionality was reimplemented, following the functor's concept, because of a problem with multiple inheritance, which occures when deriving classed which are e.g. both a camera and a panTiltUnit.
